Default TH350 Transmission leak

Hey Guys,

I have a TH350 transmission that has a small leak from the shifter linkage. Does anyone have a write up that shows how to take that linkage out and replace the O ring. I am not sure how hard of a job that is considering it is a very small leak.

Thanks

Here's some Pics I took when I changed mine. I used this tool that threads into the old seal and removes it..

It looks as simple as....

1.)remove shifter linkage
2.)remove the outer seal
3.)press the new seal over the linkage shaft


The tool you used to remove the old seal and put the new one on. Where did you get it?

Double YIKES!
I was planning on buying one too!
Maybe put me on your rental list!
Dropped the pan last year to change fluid and filter, hate to do it again, but for $100+ I probably will...

You will find the tool made by Lisle or KD listed on a bunch of websites, but they won't be able to deliver.
Mine old one disappeared last summer and eventually called the distributers and found that they were discontinued.

Ended up getting another one from Snapon, shipping is free btw and it fits all GM auto trannies.
